To all whom it may concern:

Be it known that 1, (Ann Tnoo, a subject of the King'ot Prussia, and resident of Biele'lelthlm the Province of Westphalia,- Geanan Empire, have invented new and useful Improvements in Cash-Registers, of

which the following is a specification.

The kind of cash registers to which the present invention refers is those which print, count and deliver coupons correspondingin number to themultiple which is of any predetermined amount. The invention has for its object to providemeans in combination with a cash rcgisterrforissuin coupons of a certain value adapted to collected by the customer, slich'as by pasting into a book, the; book being produced to the seller .at periodic seasons for the purpose of receivingdiscount on the amount purchased.

.For the sake of illustration the German momentary system will he taken,in which 100 pfenmgs 'areequal to lmark and it will According; to the be assumed that forsmall purchases up to sayMQflQ a number-of coupons will be delivered corresponding to the multiple of com: plete 20 pigs. in the purchase; that is in the case of apurchase ofML33 six coupons would be delivered. In order to restrict the number of coupons delivered'forgreater purchases, e. 9. 10M. and above, a single coupon is delivered and marked 10M. for each complete10Moi the purhase, this single coupon beingconveniently of a'different color to H1820 pig. coupons; 4 1,,

It is preferable to ssue'j coupons tor a round number suchuas -20pfg.,in order that the work of calculating the amount purchased may be readily accomplished by the seller when discounting, i

In cash registers of this ,kind .to employ means for printing-,1 ing the proper number of given purchase is known,

up n for a y:

v the printing and delivering?mechanisms have been operated through the mechanism' which'adds the amount purchased, which places'too great a strain on'such'adding mechanism.

present invention the coupon counting and printing mechanisms are mechanically connected to a member which is driven through a -distancdcorrespending to the'amountiof the purchase. re 5-.

More particularly the invention 'consists in a driven wheel and a driving pawl arranged to move always over a distance corresponding to-a fixed number of teeth but prevented from engaging with said teeth for any set amcuntby an adjustable uncoupling cam or the like, movable between the. wheel and the pawl, said wheel being operatively connected to the printing and delivering mechanism as .well as the coupon counting mechanism of the register The invention will bermore readily under stood from the following by way of example in the In the drawings, the money drawers, indicating mechanism and the driving crank have "been omitted.- m' suchvregisters the amount As is known, is set by pressing keys or setting levers.

As shown, the setting mechanism may comprise hand operated segments 30 mounted one shaft 31 and connected by links 32 and 33 to the tubular shafts 1., the segments 30 being retained in position, when operated, by the catches 34:, four setting seglnentlevers 3( being shown adapted to register, tons and units of marks and tons and units of pfennigs respectively.

The outer tubularshaft carries a toothed segment 2, the next inner tube carries the segment 3, the next the segi'ncnt 4:, and the innermost shaft which may be solid, carries the segment 1. It will be understood that the shafts 1 are separately rotatable and are moved by an amount corresponding to the purchase registercd.' The'segments 2, 1 and 1* gear with segments 5, 6, 7 and 7 a which are also carried on sel arate concentrically arranged shatts The toothed segments-5, (3, 7 and-7 are arranged to set types which print the amount of'the purchase on a moving strip. This strip and .the printing mechanism therefor do not form part of the present invention and are notillustrfated in the drawings.

The segments 2, 3, and (t are each pro vided with lever or arm 8, 9, and 10 respectivcly (see Figs. 1, 1 and 7),.andtheSe arms are connected by rods 11 (Figs.f.1, 1 and to the operating arm of cam plates 12, S, 1 1, which rotate on an axis 16. The axis 16 is supported between the cheek plates u und'l). The cars plates 12, 18 and i 1 1' are inthe form of segments and constitute uncoupling members. I I

On the shaft 16, three. ratchet wheels are also rotatably arranged and on theghubs of these ratchetwheels there are fixed the toothed wheels 17 18 and 19; These toothed wheels are adapted to engage with pinions 20, 21, 22 which are loosely mounted on the shaft 23 and are fixed to the type rollers= 2e, 25, 26. The roller 24 is narrow and is assumed to deliver single coupons representing each. 10M. of the purchase; the

roller25 iswicle and eachunit rotation of this roller delivers 5 coupons, each represcnting 20 pfg. of the purchase so that this roller represents the unit marks of. the purchase while the roller 26 is narrow and is assumed todeli-verone coupon for each coale'tc '20 pfgqofthe sea pfennigs in the purchese- Y On the v :scting rollers. 27, 28,29'which are and lowered by cum mechanism m I w to arises the feeding, printing and deliverj ing of the coupons.- "The coupons-ere fed trunks c from rollers d and: when" the coupons have been. fed torward and printed they ereseperated uofi, by cutting;

The operating shaft 52 in addition to operating the press,rolls 27, 28, 29 and the cuttingrnechanisrn e, is provided with cams 5 1 work. The rollers 5411;1'6 carried by rods 19, 50, 51 which connect to levers 46, 17, e8 fulcrumed at 15.. The levers 46, 17 and 18 are in turn connected by links 58 to the bent levers 55, '56, 57 which are fulcrumed on theshaift 16. Each-of the longer arms of the levers 55, 56,57 carries a pawl 59 which act with the corresponding-uncoupling cam spring 77. l

The counting mechanism (Figs. 1 and 5) is of known type comprising counting wheels 73 geared to the the counting wheels andbeing mounted on the shaft75. 76 are pawls mounted rotatably on shaft- 74 for preventing return movement of the ratchet wheels :15.

l'ows:1t will be assumed that-the register is "arranged to register purchases ranging from 1 pfg. to 99,9,9 marks. Supposing, for example, that a purchase of thevalue of 13 marks 57 pfennigs is made. 'Theoperator moves the setting lever at the right. of Fig. p6 oneplace, thereby registering 10 marks. The lever 30 to the left of this is concentric rotatable shafts 1 to be correspondingly rotated in the direction indi- ,cated by'the arrow or in 1 to various angular positions.

'Gverrunningis prevented by the shaft-61, the pawls at ti e and of their movement jamming between the shaft- 61 and ratchet wheels 15 and thus preventing further movement. The pawls corresponding to the units tllfi tens of n'iarli's always move ovcr'a (.llS- lance equal to 9 teeth but the cams '12 andonly allow the same to engage with the ratchet wheels 15 according to the'amount registered. For example, 10 marks being registered by the lever 30 regi' .ring tens is in sucn a position, that the pin 60 on the pawl 59 rides on the cam for 8 teeth and then allows the pawlzto engage and rotate the ratchet Wheel one tooth. This rotation is transmitted by the gear wheels and 22 to thetype roller 24 and rotates the same sufficiently to print one coupon of the value of 10 marks. In the case of the unit marks the pin 60 rides on the cam 1 for the first ti teeth and then allows the pawl to rotate the ratchet wheel a distance of three teeth, the rotation. being likewise transn'iitted to the type roller 25 and causing the same to rotate so as to bring three rows ct type in succession into printing position, and, the type roller adapted to print 5 coupons in. each row, 15 coupons are thereby issued, each of the value of 20 pig. The registering device for tens of pfennigs operates however somewhat differently. One coupon is issued for each complete 20 pfg. and by special arrangement of the levers (see Fig. 4) the pawl 59 corre:

sponding to the tens of fennigs only moves over 4 teeth. If there ore the lever iscauscd. to register 20 pigs. the paw 1'59 only moves over 1 tooth, and likewise when moved to register an odd number of tens of p'fennigs in the example hereinbeforc given) the pawl 59 only moves over a mum ber of teeth equal to the numberof complete '520 pig's. registered, in this case, therefore,

over 2 teeth. The type roller 26 thus prints 2 coupons each of the value of 20' pfgs. When the shaft has almost completed one revolution, the knife 6 is operated and cuts oil the printed coupons from the strips;

The number of coupons delivered is counted by means 03? the counting and registering wheels i3, 'i5 which. are actuated by the rolation of the gear wheels 17, 18 and .19 and conseqimnily in accordance with the operation of the type rollers 24;, 25 and 26; i
